What angle should a dovetail be?

The angle of a dovetail joint should be between 7 and 15 degrees: too broad and the joint won’t be strong enough, too skinny, and the pin can snap. So the angle of the dovetail mainly depends on the use and wear the joint will get. 5. They are called ‘dovetails’ because they are shaped like the tail feathers of a dove!

What is the best angle for a dovetail?

Lower (7° to 9°) angles are often advised for joining hardwoods, while higher angles (10° to 14°) are recommended for softwoods and even higher angles (14° to 18°) for half-blind dovetails.

What is the slope on a dovetail joint?

Typically the slope is 1:6 for softwoods, and a shallower 1:8 slope for hardwoods.

What are the typical angles of dovetail markers?

There is no hard and fast rule when it comes to dovetail angles. Commonly accepted ratios are 1:8 for hardwoods and 1:6 for softer timber. This 14° marker equates to a ratio of 1:4. When used with thinner stock, the 14° angle results in a better looking joint.

What is the best angle for a dovetail?

Lower (7° to 9°) angles are often advised for joining hardwoods, while higher angles (10° to 14°) are recommended for softwoods and even higher angles (14° to 18°) for half-blind dovetails.

What is the common dovetail ratio?

Dovetail angles are usually expressed as ratios — the most common being 1:6 and 1:8 (said “one in eight,” and also written as 6:1 or 8:1). As a general rule of thumb: Use 1:6 for softwoods. Use 1:8 for hardwoods.

What are the rules for dovetails?

What are the rules for dovetail joints?

The ‘pins’ are the bits of wood between the tails so there are two half-pins; one each side. The general rule is that they measure half the thickness of timber plus around a mm, so the two dots on the shoulder line are 7mm in from each edge.

What is the weakness of dovetail joint?

The disadvantages of dovetail joints are that they can be fairly difficult to mark out and cut, and if they are made badly these joints lose the advantages listed above. Depending on the project, function, and design, there are a number of different types of dovetail joints to choose from.

What is the minimum thickness for a dovetail?

Structurally I have looked for pin strength in dovetails as the dovetailed aspect is always strong because it is always at least as wide and mostly wider than the pins. In my own work I aim for a minimum size of 1/4″ and mostly 3/8″.

What is the typical angle of a dovetail metal?

Angles used on dovetails On large industrial scale machines the angle is usually 45º. For smaller dovetails the usual angle is 60º. Any less than this, i.e. 60° on a small machine, complicates the design of the adjustment mechanism. The angle produced is set by the dovetail cutter used.

What degree is a 1 8 dovetail?

So in closing your 1:4 Saddle-Tail is for all practical purposes 14 degrees, the 1:6 is close to 10 degrees and the 1:8 is about 7 degrees.

Is 11mm dovetail the same as 3 8?

The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.

What is the difference between 11mm and 3 8 dovetail?

The 3/8 Inch is measured across the bottom of the dovetail whereas the 11 mm is measured across the top of the dovetail. A 3/8 Inch dovetail is about 12.7 mm across the top. The measurements 3/8 and 11mm are not the same for this reason plus the angles are different.

What degree is a 1 8 dovetail?

So in closing your 1:4 Saddle-Tail is for all practical purposes 14 degrees, the 1:6 is close to 10 degrees and the 1:8 is about 7 degrees.

Lower (7° to 9°) angles are often advised for joining hardwoods, while higher angles (10° to 14°) are recommended for softwoods and even higher angles (14° to 18°) for half-blind dovetails.

What size is a standard dovetail rail?

Dovetails come in several different types and sizes depending on manufacturer, but the most common are the 11 mm and 3⁄8 inch (9.5 mm). Some other less known, but currently commercially available dovetail mounts, are 12, 13, 13.5, 14, 14.5, 16, 16.5, 17 and 19 mm.

Is 11mm dovetail the same as 3 8?

The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.

Is dovetail the strongest joint?

Dovetail is arguably the strongest joint in millwork. It’s made so that it can’t be twisted or pulled in any direction except for one. This means that it’ll take more force to break or damage the joint. Because of the preciseness of each piece, this joint is held into place without the need for extra reinforcement.

Is dovetail joint permanent?

The strongest and most permanent right-angled joints made in wood are the ‘dove-tail’ joints, as illustrated below. The so-called tails and pins fit together to form a secure joint. Glue may be applied to the mating surfaces.

Do you need to glue dovetails?

Michael Dresdner: The only areas that require glue on dovetails are the diagonal faces. All the diagonal faces are long grain, all the square faces are end grain, and all the flat faces abut end grain. Therefore, you need only apply glue to the diagonal faces on the tails or pins, or both.

How internal angle of dovetail can be checked?

Explanation: Formula for finding the angle of an internal dovetail is Tan A = (l2-l1/2) / h where l1 and l2 are the distance across the pins and h is the height of slip gauges. Thus by knowing these three parameters, angle A can be calculated.

What are the 2 types of dovetail joints?

Types of Dovetail Joints Half-Blind dovetails: In these, the pins and tails are hidden. Half-blind dovetails are only revealed when moved, opened or seen from a certain angle, like behind a drawer face. In a through dovetail, both the dovetails and pins are visible.

Are dovetail joints worth it?

Making sure that you pick a drawer joint that can withstand this type of wear and tear is crucial to the longevity of your kitchen cabinets. Dovetail joints are considered one of the strongest joints used in kitchen cabinetry construction and are the best solution for a kitchen cabinet drawer box.

What is the weakest joint in carpentry?

A butt joint uses a simple technique whereby two pieces of material are joined together at their ends, without any special shaping or cutting. Although it is simple, the butt joint is also the weakest of the wood joinery types.
